[0040] Specifically, as attached Figure 1 ~Attached Figure 3 As shown, a silicon material screening device, the screening component 1 comprises:

[0041] A silicon material screening box 11, with a feed hopper 111 disposed on the top;

[0042] A frame 12 is arranged on the silicon material screening box 11;

[0043] A through slot 121 is formed on the frame 12;

[0044] A motor 13 is disposed on the frame 12;

[0045] A gear 131 is arranged on the output shaft of the motor 13;

After the addition is completed, the movable plate 15 is rotatably connected to the cylindrical gear rod 14, so that the movable plate 15 can be moved to the top of the feed hopper 111. Then, the screw 16 threadedly connected to the movable plate 15 is screwed and inserted into the gear rod 14 to complete the fixation of the movable plate 15. Then, the motor 13 is started by an external power supply to drive the gear 131 to rotate. Since the gear rod 14 is meshed with the gear 131, the gear rod 14 can be driven to move up and down, and the gear rod 14 is lowered. At the same time, the baffle 18 at the bottom of the rod body 17 can be inserted into the inner side of the feed hopper 111, so as to avoid the silicon material being exposed to the outside during screening, resulting in mixing with other debris and affecting the quality of the product. The screened silicon material falls into the collecting box 19 for collection by the operator. The working principle of the silicon material screening box 11 is a mechanism for screening through an internal screen. See paragraph

[0019] of the specification of the utility model publication number "CN215613018U". The silicon material screening box 11 is common knowledge and will not be repeated here.

When the gear rod 14 moves up and down, the slide rod 26 slides inside the slide groove 25, which can limit the gear rod 14 and avoid the gear rod 14 from derailing due to operational errors, thereby increasing safety.

[0063] In one of the technical solutions disclosed in the present utility model, a second thread groove 27 is formed on the gear rod 14 and is threadedly connected to the slide rod 26 .

[0064] With the above structure, a thread groove 27 is opened on the front side of the gear rod 14 and is threadedly connected to the slide rod 26, so that the slide rod 26 can be removed from the front side of the gear rod 14 by rotating the slide rod 26, and the gear rod 14 can be pulled out from the inside of the frame 12 for replacement.

[0065] In one of the technical solutions disclosed in the present utility model, the frame 12 is connected to the silicon material screening box 11 by bolts.

[0070] It can be seen from the above description that the beneficial effects of the embodiments of the utility model are:

[0071] First, pour the silicon material to be screened into the feed hopper. After the addition is completed, the movable plate is rotatably connected to the cylindrical gear rod, so that the movable plate can be moved to the top of the feed hopper. Then, the screw threaded with the movable plate is twisted and inserted into the gear rod to fix the movable plate. Then, the motor is started by an external power supply to drive the gear to rotate. Since the gear rod is meshed with the gear, the gear rod can be driven up and down. While lowering the gear rod, the baffle at the bottom of the rod body can be inserted into the inside of the feed hopper. This can prevent the silicon material from being exposed to the outside during screening, resulting in mixing with other debris and affecting the quality of the product. The screened silicon material falls into the collection box for collection by the operator.
